## Alternative Alternative Link Positioning Solution

I think that I am getting closer and closer to having a useable solution to the link positioning problem (blog post 1, blog post 2 ). This new idea is based mostly on the last one. The idea was to use points on circles to narrow down the…

## Alternate Iterative Approach to Position Finding

In my previous blog post, about Computing the Position of a Triangle Based on Distances From External Points to Each Corner, I came up with a potential method of simulating a three link connection to a three connector link. Computing the Position of a Triangle Based on Distances…

## Computing the Position of a Triangle Based on Distances From External Points to Each Corner

? Linkage I don’t know if there is a name for this type of linkage. The green triangle link in the image above has a position (location and orientation) defined by the three ground connections and the lengths of the three connecting links. A search for equations to…

## Stephenson Valve Gear?

Upon further inspection, A Stephenson value gear mechanism cannot be built with the Linkage program. I don’t have the necessary simulation code to handle the complexity of the links. The problem comes from the connection of the “Link” to the rest of the mechanism. The position of…

## Curved Slider Path

A user asked me about curved links in the Linkage program. I think that it is safe to say that curved slider paths is the desired feature because the visual representation of a link is fairly meaningless. It is the connectors that matter. Straight Sliding Connector The straight…

## Cartesian Coordinates

Computer monitors, the old CRT kind, scan from top to bottom like a TV. Before computers, that didn’t cause any problems but when people started accessing the screen, a new coordinate system (variation) was born. It was the “inverted” Cartesian coordinate system. Well, I don’t think that there…

It turns out that moving the sample gallery into the main menu was only a little bit troublesome and only took an hour for me to figure out how to fix. The problem appeared to be that the MFC code created a new gallery window of some sort…

## New Linkage Alignment Features and Fix to The Installer

The setup program now works correctly to update the Linkage program. It turns out that there are a few more manual steps I need to take when creating the installer (MSI file) so that an update actually updates the linkage.exe executable file. Microsoft really dropped the ball when…
